There are a number of things we can do if we want to help save our planet. For example, we'll save some of the millions of trees which are cut down every year. As far as the problem of rubbish is concerned, if we recycle bottles and cans and organic waste, and stop taking plastic bags from the supermarket,this will all make a big difference. we also have to stop making unnecessary car journeys so as to cut down air pollution. try walking or using a bike instead, and if you buy local fruit and vegetables,this reduces lorry traffic to supermarkets. water is another problem, and we should all take showers, not baths, to save water. finally, we need to stop using so much energy, so try changing to low-energy light bulbs, and turning off unnecessary lights.
